ROWVLAND ROBINSON HAZARD, OF NEIV YORK, N. Y.

RAI LWAY-CAR TRUCK.

SPECIFICATION formingpart of Letters Patent No. 424,062, dated March 25, 1890.

Application filed April 2, 1837. Serial No.

To all whom it may concern:

Be it known that I, ROWLAND ROBINSON HAZARD, a citizen of the United States, and a resident of New York, N. Y., have invented a new and useful Improvement in Railway- Oar Trucks and Carriages, and in the combination of the same with each other, of which the following is a specification.

The object of my invention is to make it possible to utilize for railway service tunnels of shallower dimensions than have heretofore been found practicable for such purposes. A shallow tunnel involves only a superficial excavation, thus reducing greatly the cost of excavation. It would not endanger house foundations where a deeper tunnel would, and it can be used where, from the presence of tide-water or lake or river level, an ordinary tunnel could not be economically constructed.

I accomplish the object of my invention by the construction of an independent'cartruck or, preferably, motor-truck, adapted to be placed between the adjacent ends of two railway-cars, and to be connected thereto also by the construction of a railway car or carriage adapted to be used in connection with said truck, as hereinafter fully described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 represents. an independent motor-truck and one end of a car, both constructed in accordance with my invention. Fig. 2 represents an independent-railway-car truck and the adjacent ends of two cars connected thereto. Fig. 3 is an end View taken on line X X of Fig. 2. Fig. 4 is a figure similar to Fig. 1, showing the car beforeconnected with the truck, and in dotted lines its position when connected. Fig. 5 is a cross-section taken on line 7 7 of Fig. 4.

Referring to the drawings, 1 represents an independent railway-car truck, which in supporting the car while in motion performs the usual function of a railway-car truck, and performs also an entirely novel function in supporting two such cars while in motion or otherwise. The said truck may be of any well-known construction adapted to the purpose, and is provided with rest-blocks 2, on which the car-extensions 3 rest and are supported. The truck is coupled to the car by a coupling-pin 4 in a well-known manner.

233,372. (No model.) Patented in England September 22, 1888, No. 13,737, and in France September 22, 1888, No. 193,144.

In Figs, 1 and 4 Ihave shown an independent motor-truck 10, which performs the same functions as the independent truck hereinbefore described, and of course the additional functions of a locomotive-engine-namely, the making up of a train and drawing it when made. forms several functions which are now performed only by several different appliances and some of which are not now performed at all. It performs the principal function of a railway-carriage truck in supporting a car while in motion, and an entirely novel function in supporting two such cars while in motion or otherwise. 7

I preferably construct the carriage 5 in the manner described in my application for United States Letters Patent filed July 26, 1884, Serial No. 138,833, for unfracturable carriage. It is so formed by extensions 3 at the respective ends or at either end, or so cut away or framed that it can be combined with an independent motor-truck, Fig. 1, or with an independent supporting-truck, Fig. 2, so that the interior perpendicular dimensions of the car when in motion from the top thereof to the road-bed may be only slightly in excess of such interior dimension, permitting thereby the use of shallow tunnels involving only superficial excavations, thus reducingthe cost of excavations and enabling railway-tunnels to be constructed where, from the presence of tide-water or lake or river level, ordinary tunnels could not be economically constructed;

I provide the carriages with supplementary or safety wheels 6, calculated for use in mak ing up the trains, which wheels are removed from contact with the rails when the train is made up and in motion. In making up trains either the truck is moved under the extension of the car or the latter is moved over the truck, the height of truck and extension relative to each other being such that the one can readily pass over or under the other. Then in position, the supplementary wheels (see Fig. l) are elevated by any suitable and efieotive means, so as to clear" the track and cause the car to rest on the rest-blocks ofthe truck, as clearly shown in the drawings. The supplemental adjustable wheels also perform the function of reserve or safety wheels, which become effective by falling upon the track This independent motor-truck per and sustaining the car in the event of a break of a truck or wheel in the independent motortruck or independent car-truck.

In Fig. 4. I have not shown the wheels as adjustable relative to the car; but I have provided means 1 foravertical adjustment of the rest-blocks of the motor truck, so that by raising said blocks the carriage and its wheels can be lifted from the track. The means shown for this purpose are so simple that their construction can be understood .without a detailed description thereof.

The electric motor 8 of the motor-truck (and any suitable electric motor can be used) is connected to a wheel or wheels of the truck in any approved manner.

The construction of electric motors, their connection with drivin g-wheels,an d the means by which they are connected with the source of their power being well understood, there is no necessity for any detailed illustration or description thereof in this specification.

Having thus described my inventiomwhat I desire to claim and secure by Letters Patent is- 1. A railway car'or carriage formed at its ends with extensions arranged about midway between floor and roof, and having its floor arranged below the level of the axles of the supporting-truck, substantially as described.

A railway car or carriage provided with supplementary wheels so located as to permit the floor of the car to approach as near the road'bed as is consistent with safety and normally not in contact with the rails and formed at its ends with extensions arranged to permit the same to rest on and be supported by a truck, substantially as described.

The combination, with two adjacent cars, the floors of which are arranged below the level of the axles of the supporting-truck, of an independent railway-car truck provided with a motor, said truck supporting the adjacent ends of said cars-substantially as-described.

at. The combination, with a car or carriage provided with an extension, as described, and having its floor arranged below the level of the axles of the supporting-truck, of an independent railway-car truck provided with a motor and constructed to pass under said extension and support-:the ear, substantially as described.

In testimony whereof. I have hereunto subscribed my name.

ROWLAND ROBINSON HAZARD.
